Yes and NO your tv is a LED. To be exact it is a LED Backlight LCD TV. An LED-backlight LCD television is an LCD TV that uses LEDbacklighting instead of the CCFLs used in traditional LCD televisions. It is not a true LED display but is called "LED TV" by some manufacturers.[1] The use of LED backlighting has a dramatic impact, resulting in a thinner panel, less power consumption and heat dissipation, and a brighter display with better contrast levels.

Diana, did you ever find a solution? My Toshiba (same model) is about 2 years old and it started getting these 4 horizontal lines spaced pretty far apart and a double image at bottom. When I lightly tap the top of the TV, they went away. But now that is not working. Please let me know. Thanks.Jeff

If you mean cracked or smashed when you say "damaged", the answer is yes, but it would be far less expensive to buy a new set!We are an authorized service center for Toshiba. The replacement LCD panels are typically more expensive than the entire set was new! Go figure...

I would definetly call Sony and if it is something you can't live with return it, but remember impact damage voids the warranty, in other words if you were to drop the tv trying to return it the warranty is void.
As much as you paid for that tv it should be cosmeticly a functionaly perfect. Let me know if I can provide further assistance and please rate this solution. Lone99star

Hi, basically you need to put them into their respective slots in the back of the tv. I know this can be frustrating because the slots are all faced downwards, tucked behind this piece. Look at this image, which should be what you are seeing if you're using a Toshiba 26'' 26AV502U, a model similar to yours.http://www.bestbuy.com/site/olspage.jsp?id=cat13506&type=page&h=387&skuId=9034733&productId=1218010846690&&viewtype=backView&count=0Look at the four plugs with labeled "Video 1 In." "L Audio" is your white plug, "R" is your red plug(R actually stands for Right [Audio Input]), and Video is your yellow plug. It would be wise to remember this for every Audio/Video cable accepting unit. It makes sense you are putting the cables IN to the tv, hence "Video 1 In." Now, to tell the tv to read the video input, find and hit the "Input" button on the remote, and it should be one of those options..(there are only a couple to choose from).Hope these directions worked for you, and enlightened you!
